Consulting engineers & quantity surveyors
The takeoff that shows its work
You verify other people's tools for a living. This one is built to be verified: every quantity exposes its provenance, its confidence and its zone on the drawing.
Four mechanisms, verifiable in one sitting
The measurement comes from vectors, not a model
Areas, lengths and counts are computed in the drawing geometry. The language model names the work item and picks the unit — it never produces a number.
Every line traces back to the stroke
The review links every quantity to its zone on the drawing, both ways: click the line, the zone lights up; click the drawing, the line is found.
Doubt is a deliverable
Uncertain scale, ambiguous layer, missing dimension: the doubt is named, classified, and presented before the reliable quantities — not diluted into a global percentage.
Your deliverables stay yours
